  • FtpWebResponse and StreamReader - specifying an offset

    - by AJ
    Hi, I am using the FtpWebRequest / FtpWebResponse objects in C# to download files from a server - so far, so good. I create a StreamReader object from the response stream and use a StreamWriter to create a local file. Now, the file I am reading happens to be in a very simple 'archive' format - there is a small TOC at the start of the file followed by the actual file data. I can therefore read the TOC and get a file offset and size of the data I want to download. My question is: Supposing the offset is 1024. I would use StreamReader.Read(buffer, 1024, length), but will .NET and the FTP protocol actually allow me to skip bytes 0-1023, or does the reader still go through the (relatively) slow process of downloading and discarding the bytes I don't need? This may make the difference between whether I want to use a single archive file, or a TOC file with the data files stored separately. As a bit of a secondary question, would my mileage vary using the Http classes instead of Ftp? Cheers, Adam

  • Missunderstanding js variables

    - by meo
    I have a little problem: slideHelpers.total = 4 for (i=1;i <= slideHelpers.total; i++) { $('<a href="#">' + i + '</a>').bind('click', function(){ alert('go to the ' + i + ' slide')}).appendTo('.slideaccess') } the alert gives out 5 what is logic, because when the function click triggers i is actually 5. But i would like to have the same i as in my <a> tag. What is the best way to handle this? I could put i in the data() of the <a> tag for example but i am sure there is a easier way.

  • Uploading UIImage to server using UIImageJPEGRepresentation

    - by Thomas Joos
    hi all, I'm writing an app which uploads a UIImage to my server. This works perfect, as I see the pictures being added. I use the UIImageJPEGRepresentation for the image data and configure an NSMutableRequest. ( setting url, http method, boundary, content types and parameters ) I want to display an UIAlertView when the file is being uploaded and I wrote this code: //now lets make the connection to the web NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"return info: %@", returnString); if (returnString == @"OK") { NSLog(@"you are snapped!"); // Show message image successfully saved UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"You are snapped!" message:@"BBC snapped your picture and will send it to your email adress!" delegate:self cancelButtonTitle:@"OK!" otherButtonTitles:nil]; [alert show]; [alert release]; } [returnString release]; The returnString outputs: 2010-04-22 09:49:56.226 bbc_iwh_v1[558:207] return info: OK The problem is that my if statements does not say returnstring == @"OK" as I don't get the AlertView. How should I check this returnstring value?

  • How to bulk insert a CSV file into SQLite

    - by Lirik
    I have seen similar questions (1, 2), but none of them discuss how to insert CSV files into SQLite. About the only thing I could think of doing is to use a CSVDataAdapter and fill the SQLiteDataSet, then use the SQLiteDataSet to update the tables in the database: The only DataAdapter for CSV files I found is not actually available: CSVDataAdapter CSVda = new CSVDataAdapter(@"c:\MyFile.csv"); CSVda.HasHeaderRow = true; DataSet ds = new DataSet(); // <-- Use an SQLiteDataSet instead CSVda.Fill(ds); To write to a CSV file: CSVDataAdapter CSVda = new CSVDataAdapter(@"c:\MyFile.csv"); bool InclHeader = true; CSVda.Update(MyDataSet,"MyTable",InclHeader); I found the above code @ http://devintelligence.com/2005/02/dataadapter-for-csv-files/ The CSVDataAdapter was supposed to come with OpenNetCF's SDF, but it doesn't seem to be available anymore. Does anybody know where I can get a CSVDataAdapter? Perhaps somebody knows the much simpler thing: how to do bulk inserts of CSV files into SQLite... your help would be greatly appreciated!

  • How can I reference only a portion of a TextArea's htmlText block?

    - by Charles Shoults
    I have a number of very poor-quality pdf documents that look like 80's photocopies, which I'm rebuilding in Flash (Flex Builder 3 MXML application), representing paragraphs of text in TextAreas so that selected portions can be bold or italic, or whatever I need. I need a way to apply toolTips or event listeners to individual words within the block of text to link those words to a glossary. I'm perfectly happy to create a definition panel that is populated and made visible with a mouseOver, but don't know how to do it to just a portion of the text. Is there a good / clean / easy way to do this?

  • Select row After UIPickerView is loaded

    - by Steve Gibson
    I have an iphone database app that loads a UIPickerView with data from a table. I want to set the selected row to a particular row from the data in another table. for example: Lets say I have a UIPickerView that is loaded with X number of names of the iPhone users friends (the number of names is variable, could be 1 or 1000 and all are entered into the DB by the user). The iPhone user has a preference set that their current best friend is TED. I want the UIPickerView to be position to TED when displayed. Where do I call selectRow? I tried in viewDidAppear but it was never called, in titleForRow which caused all kinds of strange behavior. viewDidLoad and viewWillAppear are out of the question because I don't know what's in the datasource to the picker yet. Thanks in advance.

  • How do I create an Access 2003 MDE programmatically or by command line in Access 2007?

    - by Ned Ryerson
    I have a legacy Access 2003 database file that must remain in that format to preserve its menus and toolbars. I have recently moved to Access 2007 in my build environment and will be deploying the compiled Access 2003 program with the Access 2007 runtime. In Access 2003, I could script the process of creating an MDE with the Access Developer Extensions (WZADE.mde) using the command line and an .xml file of build preferences (without creating an install package). The Access 2007 developer extensions do not seem to offer a similar option. I can "Package a Solution", but it creates an accdr and buries it in a CD installer. I've tried programmatic options like Docmd.RunCommand acMakeMDEFILe and Syscmd(603, mdbpath, mdepath) but they no longer work in Access 2007. Of course, i can manually create an MDE using Database ToolsCreate MDE, but that is no scriptable as far as I can tell.

  • Rails polymorphic associations, two assoc types in one class

    - by snitko
    Consider a class: class Link < ActiveRecord::Base has_many :link_votes, :as => :vote_subject, :class_name => 'Vote' has_many :spam_votes, :as => :vote_subject, :class_name => 'Vote' end The problem is, when I'm adding a new vote with @link.link_votes << Vote.new the vote_subject_type is 'Link', while I wish it could be 'link_votes' or something like that. Is this an AR limitation or is there a way to workaround this thing? I've actually found one related answer, but I'm not quite sure about what it says: http://stackoverflow.com/questions/1168047/polymorphic-association-with-multiple-associations-on-the-same-model/1764117#1764117

  • SQL count NULL cells

    - by Giuseppe
    Dear All, I have the following problem. I have a table in a db, with many columns. I can do different kind of select queries, to show, for example, for each record that satisfies a condition: all cells from columns with names ending in _t0 all cells from columns with names ending in _t1 ... To get the column lists to form the queries I use the information schema. Now, the problem: each query returns a record with a subset of the columns of the big table. This means that I can get a row of (all!) NULLs. How can I ask my query to reject such rows without having to type in explicitely the column names (i.e. by saying where col_1 is not null, col_2 is not null...)? Is it possible? Thanks in advance!!!

  • WHERE IN Query with two recordsets in Access VBA

    - by Henry Owens
    Hi All, My first post here, so i hope this is the right area. I am currently trying to compare 2 recordsets, one of which has come from an Excel named range, and the other from a table in the Access database. The code for each is: Set existingUserIDs = db.OpenRecordset("SELECT Username FROM UserData") Set IDsToImport = exceldb.OpenRecordset("SELECT Username FROM Named_Range") The problem is that I would like to somehow compare these two recordsets, without looping (there is a very large number of records). Is there any way to do a join or similar on these recordsets? I can not do a join before creating the recordsets, due to the fact that one is coming from Excel, and the other from Access, so they are two different DAO databases. The end goal is that I will choose only the usernames that do not already exist in the access table to be imported (so in an SQL query, it would be a NOT IN(table)). Thanks for any assistance you can lend! Regards, Bricky.

  • new operator in DllMain of MFC Extension Dll

    - by Picaro De Vosio
    Hi, Dll best practices document from Microsoft available Here recommends avoiding use of memory management function from the dynamic C Run-Time (CRT) within DllMain. But DllMain function of MFC Extension DLL is dynamically allocating the memory for CDynLinkLibrary in the code snippet available at MSDN "http://msdn.microsoft.com/en-us/library/1btd5ea3%28v=VS.80%29.aspx". Is it a violation of Dll Best Practices or ok to use in MFC extension DLL? thanks

  • Outlook 2007 - Mailbox doesn't show my Items (like Calendar)

    - by cyntaxx
    Hi All, I have running an Exchange Server 2003 and 2 IBM Laptops (A&B)with XP SP3. On both Laptops Office 2007 is installed. Laptop "A" Outlook doesn't show me my Calendar and Notes entries in my mailbox tree on Laptop "A". I can click on the calenendar tab and the entries are there. On Laptop "B" it is working fine. I know that I can make a "rigth click" on "mailbox" and choose "create new folder". Than I select i.g. my calendar. It creates it, but I can't access it through my mailbox tree. Clicking on the Calendar tab works fine again. So, the mailbox is fine (I think). There must be failure with Outlook. I tried these commands here with no positive result. Outlook /cleanviews Outlook /resetfolders I want to avoid a repair installation of Outlook, because the whole office needs to be repaired. (And both laptops belong to my boss) :) Thanks, Toby

  • Install latest kernel to Ubuntu and have grub acknowledge the new installed kernel

    - by Phuong Nguyen
    I have an installed Ubuntu Distro (Karmic 9.10) already. However, due to some problems with xorg ati driver, I cannot standby my computer. Some guy have suggested me to try the latest version of xorg driver which in turn requires a newer version of Linux kernel than the newest release available from Ubuntu Central Repository (2.6.33). I have searched though several articles on how to install a custom Linux kernel. However, these articles are so 2004/2005 and they were talking about lilo (???). Since then, I'm afraid that I cannot make the Grub Boot recognize the new Linux kernel properly (I'm just a newbie to Linux). I would love to know how to install the kernel into Ubuntu and have grub acknowledge the new installed kernel.
